Mongolian President Nambaryn Enkhbayar said (2005 November) that China and Mongolia have reached a final agreement on the exact demarcation of their 4,677-kilometer border, the longest for both countries.

After four years of talks, Enkhbayar signed a series of border-related agreements with Chinese leaders in Beijing, giving Mongolia for the first time in recent history a fully defined national boundary.

The two countries also agreed to install 1,513 border demarcation posts, Enkhbayar said at a press conference in Beijing.
